VETERINARY FLOAT.

Specification of Letters Patent.

Patented Jan. '7, 1908.

Application filed January 26. 1906. Serial No. 298,012.

T o all whom it 'may concern.'

Be it known that l, Davie O. liNrsnLY, a citizen of the United States,residing at Topeka, in the county of Shawnee and State of Kansas, haveinvented a new and useful Veterinary Float, of which the following is aspecification.

This invention relates to veterinary floats.

The object of the invention is to provide a float which will in a noveland rapid manner and without danger of lacerating the jaws of the animalgrind away teeth with equal facility in any part of the mouth or ineither jaw.

WVith the above and other objects in view, as will appear as the natureof the invention is better understood, the same consists in the novelconstruction and combination of parts of a veterinary float, as will behereinafter fully described and claimed.

ln the accompanying drawings formimg a part of this specification and inwhich like characters ofl reference indicate corresponding arts Figure 1is a view in perspective, part y in section of a float constructed inaccordance with the present invention. Fig. 2 is a view in transversesection through the head 0f the float. Fig. 3 is a detailed sectionalview of the grinding element.

The float constitutes a tubular shank 1, at one end of which is secureda hollow head 2 provided with spaced lateral guards 3 cxtendinglongitudinally of the head and operating in the well known manner toprevent the flesh of an animals aw froln coming in contact with thegrinding element.

Housed in the shank is a shaft 4 one end of which carries a grindingelement 5, and the other end of which projects through a journal boX 6,the projecting end of the shaft being provided with an orifice 7 bywhich it can be connected with an ordinary flexible drive shaft notnecessary to be shown.

As shown in Fig. 2, the guards 3 define a channel through which projectsthe grinding element 5 but the periphery of the latter occupies a planebelow the edges of the guards so that danger of laceration of the Ileshwill be reduced to a minimum.

The grinding element which constitutes one of the essential features ofthe present invention is constructed of carborundum and is in thefornr-of a cylinder and is mounted upon the outer terminal 8 of theshaft that lies within the head and is held against movement thereon vbya collar 9, rigid with the shaft and which operates to prevent the shaft'from having any endwise movement, and a nut l() screwed upon the outerterminal of the shaft, but lying within the head, thus to be held out ofcontact with the Vfleshy parts of an animals jaw.

lt willv be observed by reference to Fig. 1 that the terminals of thegrinder are inset from the ends of the head. The object of thisarrangement is to permit the grinding off of sharp corners by the saidterminals that are not :weessible to the other portion of the grinderand under such conditions the implement will have to be rocked, with thetooth as a pvot, and when this operation is observed, the guards operateas guides to hold the grinder in engagement with the portions of thetooth to be removed.

The advantage of carboruiulum as a grinding element over an ordinaryille, such as is commonly employed, is that there will be no jumping andjarring when the element strikes a hard part of a tooth or a projectinglportion thereof, which inevitably results where a `file is used, andwhich not only causes discomfort to the animal, but is also attended byrough breaks or chips of the tooth and thus the presentation of sharpcorners, which cut the aws and tongue of the animal. Owing to itseXtreme hardness, thc grinding element 5 will not be perceptiblyeffected by the enamel of the teeth, so that,

' barring breakage, one grinding element may be used for an extendedperiod, whereas the ordinary file soon dulls and is thus renderedworthless.

Wvhile the improvements herein defined are simple in character, theywill be found to result in the production of an implement having thehighest cutting qualities and one that may be used `for an extendedperiod without danger of derangement or breakage.

A '.loat comprising a hollow head provided with spaced longitrulinallydisposed guards, a cylindrical carborun du m grinder housed by the headand having its circumference lying within the edges of the guards andits terminais inset from the ends of the head to permit the guards toact as guides When the implement is rocked in rounding off roughoorners, a shank rigid With the head7 and a shaft rotatable Within theshank and seoured to the grinder.

In testimony that I claim the foregoing as DAVID O. KNISELY.
